Appendix A
Description of Munitions in the Pueblo Chemical Depot Stockpile
Figures A-1 through A-3 are cutaway drawings of the 105-mm shell, 155-mm shell, and 4.2-inch mortar projectiles. Information is also included on the size, weight, energetics, and packaging of each projectile.
The stockpile inventory at Pueblo Chemical Depot consists entirely of munitions containing mustard agent. Most of the projectiles contain mustard agent HD (distilled ß,ß'-dichloroethyl sulfide). Some contain mustard agent HT, a 60:40 eutectic mixture of HD and bis(2-[2-chloroethylthio]ethyl)ether. All of the munitions may contain some degradation products and inorganic residues.
